This is to the same purport with what we had Pro 16:14, Pro 16:15, and the design of it is, 1. To make kings wise and considerate in dispensing their frowns and smiles. They are not like those of common persons; their frowns are very terrible and their smiles very comfortable, and therefore it concerns them to be very careful that they never frighten a good man from doing well with their frowns, nor ever give countenance to a wicked man in doing ill with their smiles, for then they abuse their influence, Rom 13:3. 2. To make subjects faithful and dutiful to their princes. Let them be restrained from all disloyalty by the consideration of the dreadful consequence of having the government against them; and let them be encouraged in all good services to the public by the hopes of the favour of their prince. Christ is a King whose wrath against his enemies will be as the roaring of a lion (Rev 10:3) and his favour to his own people as the refreshing dew, Psa 72:6.

The king's wrath is as the roaring of a lion,.... Which is very terrible when hungry, and is after its prey, and has got it. Kings, especially tyrannical ones, are compared to lions; as Nebuchadnezzar by Jeremiah, Jer 4:17; and Nero by the Apostle Paul, Ti2 4:7; and the rage of such is very dreadful, as Ahasuerus's was to Haman. Jarchi interprets the king, of the holy blessed God. It may be applied to Jesus Christ, the Lion of the tribe of Judah; who is said to cry with a loud voice, as when a lion roareth; and whose wrath is terrible to wicked men, and even to the kings of the earth, Rev 5:5;

but his favour is as dew upon the grass; which refreshes and revives it, and causes it to grow and flourish: and so the favour and good will of a king to his subjects delights them, and causes joy and cheerfulness in them; and such an effect has the love of God and Christ on the children of men, Hos 14:6.

(Compare Pro 16:14-15; Pro 20:2). A motive to submission to lawful authority.
